Okay, I currently have my i7 clocked at 4.6ghz across all cores with a voltage of 1.240, would you consider that an average or good chip?
I'm thinking what's the highest voltage you would recommend for 24/7 I'm going to try for 4.8 at 1.3 I know it can bench 4.9 at 1.350 but isn't prime stable after an hour.... maybe 1.375 could do it, seems a bit too high for me though, So I'm wondering to get the most out of my cpu would it be okay to have the voltage around no more than 1.325 for 4.8 using a corsair h105 with cool laboratory thermal paste and it's doing the job pretty well with an evga G2 1000 watt power supply. Any help greatly appreciated :)
 
I don't see the point in pushing for anything over 4.5ghz as the gains are marginal. I would, personally and like I'm already doing, run it with a vCore offset and look at 4.5-4.6ghz.

Thank you for the response I've currently got it at 4.6 1.240 volts and idles around 27 degrees and as low as 18 in the BIOS (very cold here in Liverpool) and under load it's around 60 degrees, overall fantastic chip and I'd like this to last me for a good 5 years! :)
 
cheers matey, it's done 7 hours prime 95, ran through benchmarks all the cinebench, it's done intel burn test for one run and it's been playing all my games with no hickups :D :)

I really wish people would read other threads before using these programs. IBT doesn't create a realistic environment. It just stresses the CPU for no reason. CineBench is different but if your overclock is stable while gaming, you've got nothing to worry about :)

No digging at you, its the 3rd thread I've read where the CPU is being stressed for no reason.

cheers mate :) I had it crash on me 4 hours into prime at 1.230 volts so even though that MAY have done me I still wouldn't want to run it knowing it's capable of crashing :)
 
Prime and IBT and not great for Haswell.

Try Cinebench but as mentioned, if no problems and good temps then its fine.
 
If your cooling is up to it i would just crack on with the overclocking, sounds like your chip is similar to mine in performance, mine runs at 4.8 with 1.3v and 4.9 with 1.36. As long as your cooler can handle it whilst staying quiet then i wouldnt be happy stopping 300mhz short of a comfortable overclock. Maybe thats just me :)

I'm using the older version of prime 95 that doesn't run the special instructions :) I'm just going to stick with the 4.6ghz for it to last me some years to come :)
 
Dont use prime on a 4790k, You are damaging your chip to a totally pointless cause. Prime does not reflect any sort of real life situation. Prime is known to degrade Haswell very quickly. My advise never run it again. Just bench and play simples.
